This invention relates to wire twisting verse ridge is a bearing member24 adapted machines for twisting the ends of binding wires onto articles of any description.

One object of the invention is to provide amachine that will secure wire to the articles by twistin and will perform this function in a far more efficient manner than that of manual twisting.

Yet another object of the invention is to 310 provide a machine that will quickly tie the wire to the article by twisting, thereby resulting in a saving of time and labor in job lots.

A further object of the invention is to provide a machine that is inexpensive to manufacture and one which may conveniently be attached to the ordinary workshop bench.

With these and other objects in view, which will more readily appear as the nature of the invention is better understood, the same consists in the novel construction, combination and arrangement of parts shown in the accompanying drawings, in which:

Fig. 1 is a perspective view of the device shown attached to a work bench.

Fig. 2'is a perspective view of one of the articles prior to the twisting operation. Fig. 3 is a perspective view of the same article, after the twisting operation has been performed, and 7 Fig.4 is a sectional view showing the method of attachment of the article holder to a work bench. v

In all of the above mentioned views, like characters of reference are employed. to designate like parts and the work bench is shown at 10. This bench is of the usual type. Secured in any suitable manner, as for example, by means of wood screws 12, is a work holder 14. This holder is in the form of a block having a reduced portion 16 adjacent the bench for the purpose of holding the articles to be tied. The-reduced portion 16 has a groove 18 therein to receive the end of the binding wire 19. Designated at 20, is a transverse slot prothe article holder. Mounted on this transdotted line position 64. 'inally maintained in an elevated position viding a transverse ridge 22 at one end of j I V rotating the gear 26 and twistlng the wire to rotatably support a grooved shaft 25, having a 'gea-r 26 thereon. This gear is grooved at 28 to receive the'binding wire.

In order to hold the article to be tied, an arm 30 is pivoted to a bracket 32 on the work bench 10. This arm has a lateral head 34, which head is provided with a groove 36 to accommodate the binding wire 19. The arm 30 is of sufiicient length that the head will just clear the edge of the work bench.. The arm has a pull rod 38 secured thereto and this rod extends clownwardly through an aperture 40 in the bench to a point adjacent the floor, where the same is secured to a foot pedal 42 pivoted to the floor. Thus, it will be seen that motion of the pedal downwardly will operate to bring the head 34 into contact withv the article a, in the groove 16, to be tied. The 70 pedal 42 is maintained normally in an elevated position by means of the spring 44, which is secured in any suitablemanner to a convenient stationary point on the bench.

Slidably secured to a support 46 is a rack 7 48 having lateral flanges 5Ov slidable in a bracket 52. This rack is toothed at 54 to mesh with the gear 26. The lower end of the rack has a pull rod 56 secured thereto,

which rod is slidable in a bushing 58 embedded in the floor. The bushing is provided with a stop collar 60 and a stop element 62 secured to the rod 56. The slidable rod 56 has secured thereto a pedal 64 which is located at a point. somewhat above the floor. This pedalmay beturned intothe The pedal is norby means of the spring 68 secured to the work bench. i

In actual operation one of the articles, designated at a in Fig. 2, is placed in the groove 16 of the article holder 14, as previously described with the Wire 19 in the grooves 25, 28 and 86. Movement of the pedal 42 downwardly will bring the head 34 into contact with the article a to be tied. The operator now depresses the pedal 64, which draws the rack 48 downward for onto the article a under treatment. The operator now removes his foot from the pedal 42 permitting the spring 44 to elevate the article clamping lever 30 and release the article a, whereby it may now be removed. He now removes his foot from pedal 64. The spring 68 pulls the rack 5% upward, which. rotates the pinion 26 to bring the groove 28 in line with the grooves 18 and 24. This position of the gear pinion is determined-by the stop 62 engaging the bushing 60. The machine is now ready for the next operation to be repeated. When,

the pedal 64 is depressed, the collar 56, which is secured to the rod-56, will pull this rod and rack 54: downward. The dotted line position 645, of the pedal ea is the preferred position, as it may be turned on the rod 56.
